5" Carbon Filters

We carry two brands of 5 inch carbon filters at Greens; the budget friendly Prima Klima filters and the high performing Rhino Pro filters. Both do a great job at trapping and neutralising those unwanted odours in your grow room.

Rhino Pro Filter

Rhino Pro filters are the premium filters to use for horticultural purposes. In our opinion, these filters are by far the market leaders. Built with high-performance in mind, Rhino Pro filters are constructed from lightweight aluminium and use extremely high quality carbon.

The activated carbon used is Australian-mined Tiwest RC124 which is the purest activated carbon available in the world. It is super effective at odour control, will provide excellent filtration for at least two years, and works well in both high and low humidity environments.

The 5 inch carbon filter from Rhino Pro is suitable for use with both low-power and high-power fans. It is highly important to match your fans with the right carbon filter as a mismatch will make for less effective odour control and will reduce the lifespan of your ventilation equipment.

Prima Klima Filter

German manufacturer Prima Klima makes a great range of affordable yet effective carbon filters. This budget 5 inch carbon filter is suitable for use with low powered fans only. Although called a ‘budget’ filter, it is still made to Prima Klima’s high standards; using high-grade activated carbon derived from pit coal.

Apart from a marginal difference in odour control, the main difference between these budget filters and the Rhino Pro filters is lifespan. Prima Klima filters should be replaced every nine to twelve months whereas a Rhino Pro will easily last for two years or longer before it needs to be replaced.

Rhino Hobby Filters

Offering probably the best value for money of any carbon filter on the market, these 5 inch filters cost just £29.95. Airflow wise they can clean around the same as the mopre expensive Rhino Pro Filters of the same size, but will only last for around 12 months of normal use. You will need to turn these filters every 3 or 6 months to get the most out of the carbon.

5" CARBON FILTERS FAQ's:

How Do Carbon Filters Work?

Carbon filters work by utilising the features of activated carbon. This type of carbon has been oxidised which gives it a massive surface and super adsorbent properties.

To give you an idea of just how effective active carbon is; a single gram of the stuff has a surface area larger than 500 m2. Five grams will give you roughly the same surface area as a football pitch.

The massive surface area of activated carbon ensures that any unwanted odours flowing through your carbon filter will be effectively trapped and neutralised.
